Description
The Knight’s Armament SR-15 Ambi Lower gives builders a forged, ambidextrous foundation with the trigger guard and takedown pins already in place. Built for shooters who want proprietary ambi controls without starting from a bare receiver, this lower streamlines the build process while keeping KAC’s signature ergonomics.
Features:
- Forged 7075-T6 aluminum construction
- Type III hardcoat anodized finish
- Rollmarked “SR-15” and “5.56mm” designations
- Proprietary ambidextrous bolt catch/release
- Ambidextrous safety selector and magazine release
- Integrated trigger guard pre-installed
- Pivot and takedown pins included
- Compatible with standard mil-spec small parts and triggers
This lower ships partially assembled, with the ambidextrous controls, trigger guard, and takedown pins already installed, so builders can move straight to dropping in a parts kit and stock without machining or additional fitting. The receiver is rollmarked with “SR-15” and “5.56mm” designations and finished in a Type III hardcoat anodize for added wear resistance. The proprietary right-side bolt release is unique to the KAC design and works alongside standard mil-spec small parts and triggers, which fit the lower pocket without modification, giving builders flexibility in how they finish the rest of the build.
Knight’s Armament Company has built a reputation supplying precision rifle systems to military and law enforcement units, and its SR-15 platform reflects that same focus on reliability and ergonomics. The company’s ambidextrous control layout has become a recognizable feature among shooters looking for a more universally accessible manual of arms.
